Description

Technical Field

[0001] The utility model belongs to the technical field of machine tool processing, and particularly relates to a chip conveyor and filter device for a machine tool. Background Art

[0002] With the rapid development of gear milling machines, they are widely used not only in the civilian automotive manufacturing industry to improve the processing efficiency and product high precision of automotive parts, but also provide core mother machines for China's aerospace and military industries, which are the cornerstones of heavy vehicle manufacturing in the country. Gear milling machines achieve efficient and high-precision delivery by finely removing materials and performing multiple fine machining operations on the gear meshing surfaces.

[0003] The chips generated by gear milling machines are different from the chip shapes of machining centers, turning, drilling, and grinding. Most of the chips processed by gear milling are small flakes and needles. Under the flushing of the oil, the chips with light self-weight will be in a suspended state. Such suspended chips cannot be removed by existing chip conveyors, which increases the blockage rate of the external filtration unit and requires frequent manual maintenance of the filtration unit; even if a filtration unit with self-cleaning function is used, there are still needle-like small chips entering the filtration water tank. After using for a period of time, due to the slow flow rate in the water tank, a large amount of chips will precipitate at the bottom of the water tank, and the water tank needs to be frequently cleaned and maintained. If not cleaned for a long time, there will be more and more deposited chips around the water pump suction port, resulting in a sharp reduction in the water tank volume and affecting the normal operation of the entire machine tool cooling system. At the same time, the workpieces processed by gear milling machines are relatively small, resulting in a relatively small floor space occupied by the gear milling machine itself, and the external dimensions of the chip conveyor also need to be compact. Therefore, a chip conveyor with a compact structure, rapid chip removal, and water tank maintenance-free is needed. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a chip conveyor and filter device for a machine tool. The technical solution adopted by the utility model is as follows:

[0005] A chip conveyor and filter device for a machine tool includes a chip conveyor device and a magnetic separation device;

[0006] The chip conveyor device includes a housing, a driving mechanism, a driving motor, a rotary mechanism, a driving chain, and a scraper; the rotary mechanism and the driving mechanism are respectively arranged at the front and rear ends inside the housing, and the driving mechanism is driven by the driving motor; the driving chain is arranged between the rotary mechanism and the driving mechanism, and a plurality of scrapers are arranged on the driving chain, and the scrapers are in contact with the bottom surface of the housing; an inlet for chips is arranged at the front end of the upper surface of the housing, and a chip discharge port is arranged at the lower part of the rear end surface of the housing;

[0007] The magnetic separation device includes a magnetic roller, a motor, a chip scraping plate, a liquid receiving box and a chip receiving box; the magnetic roller is located behind the chip discharge port, and the magnetic roller is connected to the motor; the liquid receiving box is located below the magnetic roller, and two side plates are provided on the liquid receiving box, and the magnetic roller is arranged on the two side plates through bearings; a liquid receiving port is provided on the upper surface of the liquid receiving box, and a concave surface is formed between the chip discharge port and the liquid receiving port, and a fluid channel is formed between the concave surface and the magnetic roller; the chip scraping plate is fixedly arranged on at least one side plate obliquely, the upper end of the chip scraping plate abuts against the surface of the magnetic roller, and the chip receiving box is arranged below the chip scraping plate.

[0008] The above technical features of this solution have the following technical effects:

[0009] In the chip scraping and filtering device of the machine tool of the present utility model, during operation, the chips and cutting fluid discharged from the machine tool enter from the chip inlet. Larger chips rely on the gravity of the chips to precipitate to the bottom of the housing, and then the scraper is driven by the drive chain to collect the chips precipitated to the bottom of the housing and convey them to the chip discharge port in the direction of the magnetic roller. After being discharged with the cutting fluid, they are adsorbed by the rotation of the magnetic roller, and then scraped off by the chip scraping plate and collected into the chip receiving box. The chips that are too light in self-weight and enter from the chip inlet cannot precipitate to the bottom of the housing, and the chips will flow with the cutting fluid. When the chips flow out from the chip discharge port with the cutting fluid and then pass through the fluid channel formed between the concave surface of the liquid receiving box and the magnetic roller, they will also be adsorbed by the rotation of the magnetic roller, and finally scraped off by the chip scraping plate and collected into the chip receiving box. The fluid channel formed between the concave surface of the liquid receiving box and the magnetic roller reduces the distance between the chips and the magnetic roller, and the chips will flow through the fluid channel with the cutting fluid, increasing the contact time between the chips and the magnetic roller. The rotation direction of the motor is opposite to the rotation direction of the drive motor, so that the rotation direction of the magnetic roller is different from the flow direction of the cutting fluid when it flows through the fluid channel, increasing the time for the cutting fluid to flow through the fluid channel and increasing the contact time between the chips and the magnetic roller. The reduction of the distance and the increase of the contact time enable the small chips with too light self-weight to be adsorbed and processed cleanly by the magnetic roller. After the cutting fluid is filtered by the magnetic roller and there are no adsorbable chips inside, it flows into the liquid receiving box through the liquid receiving port. It can be seen that the chip scraping and filtering device of the new machine tool of the present utility model can clean all the chips, large and small, in the cutting fluid, without the need for frequent cleaning and maintenance in the later stage, improving efficiency, reducing maintenance costs and maintenance costs, and having a compact structure.

[0010] This technical solution can also be improved as follows:

[0011] Further, a stainless steel cylinder is provided outside the magnetic roller, and a magnetic material is installed on the inner wall of the stainless steel cylinder.

[0012] The above further technical features have the following technical effects: It can realize that the entire stainless steel cylinder outside the magnetic roller can adsorb chips, increasing the adsorption area.

[0013] Further, a plurality of magnetic boxes are evenly distributed on the inner wall of the stainless steel cylinder, and the magnetic boxes contain magnetic materials.

[0014] Further, magnetic roller gland covers are provided at both ends of the stainless steel cylinder.

[0015] Further, the slewing mechanism is a slewing guide rail or a gear.

[0019] Further, a plurality of through holes are arranged at intervals on the scraping plate to reduce the resistance of the cutting fluid.

[0026] In order to better understand the purpose, structure and function of the present utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] First Embodiment:

[0028] As Figures 1-3As shown in the figure, a chip scraping and filtering device for a machine tool includes a chip scraping device and a magnetic separation device. The chip scraping device includes a housing 1, a driving mechanism 2, a driving motor 3, a rotary mechanism, a driving chain 5 and a scraper 6. The rotary mechanism and the driving mechanism 2 are respectively arranged at the front and rear ends inside the housing 1, and the driving mechanism 2 is driven by the driving motor 3. The driving chain 5 is arranged between the rotary mechanism and the driving mechanism 2. The rotary mechanism is a rotary guide rail 4. A plurality of scrapers 6 are arranged on the driving chain 5. The scraper 6 is a flat scraper, and the scraper 6 abuts against the bottom surface of the housing 1. An inlet 7 is arranged at the front end of the upper surface of the housing 1, and a discharge port 8 is arranged at the lower part of the rear end surface of the housing 1.

[0029] The magnetic separation device includes a magnetic roller, a motor 10, a chip scraping plate 11, a liquid receiving box 12 and a chip receiving box 13. The magnetic roller is located behind the discharge port 8. A stainless steel cylinder 9 is arranged outside the magnetic roller. Magnetic roller gland covers 19 are arranged at both ends of the stainless steel cylinder. A plurality of magnetic boxes 21 are evenly distributed on the inner wall of the stainless steel cylinder 9. In this embodiment, seven magnetic boxes 21 are provided. The magnetic boxes 21 contain a magnetic material 18. In this embodiment, the magnetic material 18 is a strontium ferrite magnetic material, which can enable the whole stainless steel cylinder 9 to adsorb chips, increasing the adsorption area. The liquid receiving box 12 is located below the magnetic roller. Two side plates 17 are arranged on the liquid receiving box 12. The magnetic roller is arranged on the two side plates 17 through a bearing magnetic roller shaft 20. A liquid receiving port 16 is arranged on the upper surface of the liquid receiving box 12. A concave surface 14 is formed between the discharge port 8 and the liquid receiving port 16. A fluid channel 15 is formed between the concave surface 14 and the magnetic roller. The magnetic roller is connected to the motor 10. The chip scraping plate 11 is obliquely fixed on at least one side plate 17. The chip scraping plate 11 is made of stainless steel. The upper end of the chip scraping plate 11 abuts against the surface of the magnetic roller. The chip receiving box 13 is arranged below the chip scraping plate 11. Among them, the rotation direction of the motor 10 is different from that of the driving motor 3.

[0030] In addition, a number of through holes can also be arranged at intervals on the scraper 6 to reduce the resistance of the cutting fluid.

[0031] When the machine tool scraping chip removal and filtering device of the utility model is working, the chips and cutting fluid discharged from the machine tool enter from the chip inlet 7. Larger chips rely on the gravity of the chips to precipitate to the bottom of the housing 1, and then the driving chain 5 drives the scraper 6 to collect the chips precipitated to the bottom of the housing 1 and convey them to the chip discharge port 8 in the direction of the magnetic roller. After being discharged with the cutting fluid, they are adsorbed on the surface of the stainless steel cylinder 9 by the rotation of the magnetic roller, and then scraped off by the chip scraping plate 11 and collected into the chip receiving box 13. The chips that are too light in self-weight and enter from the chip inlet 7 cannot precipitate to the bottom of the housing 1. The chips will flow with the cutting fluid. When the chips flow with the cutting fluid through the fluid channel 15 formed between the concave surface 14 of the liquid receiving box 12 and the magnetic roller and are discharged from the chip discharge port 8, they will also be adsorbed on the surface of the stainless steel cylinder 9 by the rotation of the magnetic roller, and finally scraped off by the chip scraping plate 11 and collected into the chip receiving box 13. The fluid channel 15 formed between the concave surface 14 of the liquid receiving box 12 and the magnetic roller reduces the distance between the chips and the magnetic roller. The chips will flow through the fluid channel 15 with the cutting fluid, increasing the contact time between the chips and the magnetic roller. Coupled with the fact that the rotation direction of the motor 10 is different from that of the driving motor 3, the rotation direction of the magnetic roller is different from the flow direction of the cutting fluid when it flows through the fluid channel 15, which can further increase the contact time between the chips and the magnetic roller. The reduction of the distance and the increase of the contact time enable the small and light chips in self-weight to be adsorbed and processed by the magnetic roller more cleanly. After the cutting fluid is filtered by the magnetic roller and there are no chips that can be adsorbed inside, it flows into the liquid receiving box 12 through the liquid receiving port 16. It can be seen that the machine tool scraping chip removal and filtering device of the utility model can cleanly process all chips, large and small, in the cutting fluid, without the need for frequent subsequent cleaning and maintenance, improving efficiency, reducing maintenance costs and maintenance costs, and having a compact structure.
